Researchers to track impact of lockdown on alcohol, gambling and pornography use

̽��ֱ��UK was first placed on lockdown in response to the coronavirus pandemic on 23 March. Only essential businesses were allowed to remain open and everyone was told to stay at home, only to venture out for exercise and shopping.

Almost overnight, people’s lives were up-ended, with some people working from home while others have lost their jobs or been furloughed. People who live by themselves have suddenly found themselves with no social contact other than virtual.

To find out what impact this has had on people’s behaviour, Dr Valerie Voon from the ̽��ֱ�� of Cambridge and Prof Henrietta Bowden-Jones, Director of the National Problem Gambling Clinic, London, have launched an online survey, HabiT – Habit Tracker – asking about changes in habits during lockdown, specifically quantifying alcohol, smoking, and online use of gambling, gaming and pornography. ̽��ֱ��habit tracker survey is available online. All responses will be anonymous.

̽��ֱ��survey is short, only taking 10 minutes to complete. ̽��ֱ��researchers are keen to hear from both those people who do not consider themselves to be vulnerable or exhibit problem behaviours and those who have struggled in the past or are struggling now.

“We expect to see an increase in these behaviours across the UK in response to the unprecedented circumstances we find ourselves in,” says Dr Voon. “In many cases, these changes will be people’s strategies for coping with the anxiety and stress caused by the pandemic and lockdown and, we hope, won’t have a long term impact if the behaviour can be controlled.

“For some people who might already have been struggling with or have a history of addiction these increased habits could prove problematic. ̽��ֱ��same goes for those people who find themselves in difficult circumstances, for example having lost their job or facing financial difficulties, or are struggling to cope with the lockdown. These more vulnerable individuals may find their behaviour has a more marked longer lasting effect, triggering an alcohol relapse, for instance, or reigniting a gambling addiction.”

Survey respondents may also take part in CrusH, an alcohol avoidance online training game for smartphones being developed which can be accessed as part of the survey.

Five tips for coping during the lockdown

Keep active: exercise outdoors and take part in online exercise workouts
Keep in touch with people socially online – try FaceTime, Skype or Zoom so that you see people
Maintain some regular structure: sleep, wake, work
Don't spend too much time looking at news
Use this as an opportunity to try something new – try baking, learning a new language, writing that novel you always dreamed of writing

Is the lockdown leading us to drink more alcohol or spend more time gambling online or watching pornography? Researchers today launch a survey aimed at tracking how our habits have changed in response to our forced isolation.

Online porn may feed sex addicts’ desire for new sexual images

cjb250 — Mon, 23 Nov 2015 12:12:04 +0000

In a study published in the Journal of Psychiatric Research, researchers also report that sex addicts are more susceptible to environment ‘cues’ linked to sexual images than to those linked to neutral images.

Sex addiction – when an individual has difficulty controlling their sexual thoughts, feelings or behaviour – is relatively common, affecting as many as one in 25 young adults. It is heavily stigmatised and can lead to a sense of shame, affecting an individual’s family and social life as well as their work. There is no formal definition of the condition to help with diagnosis.

In previous work led by Dr Valerie Voon from the Department of Psychiatry at the ̽��ֱ�� of Cambridge, scientists found that three brain regions were more active in sex addicts compared with the healthy volunteers. Significantly, these regions – the ventral striatum, dorsal anterior cingulate and amygdala – were regions that are also activated in drug addicts when shown drug stimuli.

In the new study, funded by the Wellcome Trust, Dr Voon and colleagues studied the behaviour of 22 sex addicts and 40 ‘healthy’ male volunteers undergoing tasks. In the first task, individuals were shown a series of images in pairs, including naked women, clothed women and furniture. They were then shown further image pairs, including familiar and new images, and asked to choose an image to ‘win £1’ – although the participants were unaware of the odds, the probability of winning for either images was 50%.

̽��ֱ��researchers found that sex addicts were more likely to choose the novel over the familiar choice for sexual images relative to neutral object images, whereas healthy volunteers were more likely to choose the novel choice for neutral human female images relative to neutral object images.

“We can all relate in some way to searching for novel stimuli online – it could be flitting from one news website to another, or jumping from Facebook to Amazon to YouTube and on,” explains Dr Voon. “For people who show compulsive sexual behaviour, though, this becomes a pattern of behaviour beyond their control, focused on pornographic images.”

In a second task, volunteers were shown pairs of images – an undressed woman and a neutral grey box – both of which were overlaid on different abstract patterns. They learned to associate these abstract images with the images, similar to how the dogs in Pavlov’s famous experiment learnt to associate a ringing bell with food. They were then asked to select between these abstract images and a new abstract image.

This time, the researchers showed that sex addicts where more likely to choose cues (in this case the abstract patterns) associated with sexual and monetary rewards. This supports the notion that apparently innocuous cues in an addict’s environment can ‘trigger’ them to seek out sexual images.

“Cues can be as simple as just opening up their internet browser,” explains Dr Voon. “They can trigger a chain of actions and before they know it, the addict is browsing through pornographic images. Breaking the link between these cues and the behaviour can be extremely challenging.”

̽��ֱ��researchers carried out a further test where 20 sex addicts and 20 matched healthy volunteers underwent brain scans while being shown a series of repeated images – an undressed woman, a £1 coin or a neutral grey box.

They found that when the sex addicts viewed the same sexual image repeatedly, compared to the healthy volunteers they experienced a greater decrease of activity in the region of the brain known as the dorsal anterior cingulate cortex, known to be involved in anticipating rewards and responding to new events. This is consistent with ‘habituation’, where the addict finds the same stimulus less and less rewarding – for example, a coffee drinker may get a caffeine ‘buzz’ from their first cup, but over time the more they drink coffee, the smaller the buzz becomes.

This same habituation effect occurs in healthy males who are repeatedly shown the same porn video. But when they then view a new video, the level of interest and arousal goes back to the original level. This implies that, to prevent habituation, the sex addict would need to seek out a constant supply of new images. In other words, habituation could drive the search for novel images.

“Our findings are particularly relevant in the context of online pornography,” adds Dr Voon. “It’s not clear what triggers sex addiction in the first place and it is likely that some people are more pre-disposed to the addiction than others, but the seemingly endless supply of novel sexual images available online helps feed their addiction, making it more and more difficult to escape.”

People who show compulsive sexual behaviour – sex addiction – are driven to search more for new sexual images than their peers, according to new research led by the ̽��ֱ�� of Cambridge. ̽��ֱ��findings may be particularly relevant in the context of online porn, which potentially provides an almost endless source of new images.
